WALL CONSTRUCTION.

Application. filed January 1e, 1925.I serial No. 2,853.

To all fio/wm. t muy concern.'

Be it known that l, AN'roN MARIUS CnAMnn, a subject of the King of Denmark, and residing at the eity of Montreal, in the `Province of Quebec in the Bominion of Canada, have invented a new and useful lVall Constrndtion7 of which the following is the specification.

The invention relates to Wall construction, as described in the present specification and illustrated in the. accompanying drawings that form part of the Same.

The invention consists essentially of' the novel features of construction pointed out broadlyT and specifically in the claims for novelty following a description containing an explanation in detail of an acceptable forni of the invention.

rlhe objects of the invention are to eliminate the bad effects or open joints in ceinent concrete or other block Walls and thereby insure Warmth and security in the interior of a house or other building; to increase to the utmost limit the air spaces between inner and outer blocks of the wall;r and generally to provide an economical. durable and etficient construction.

In the drawings Figure 1 is an elevation of the Wall construction.

Figure 2 is a vertical sectional view on the line 2 2 in Figure 1.

Figure 3 is a horizontal sertioi'ial view on the line 3--3 in Figure 1.

Figure l is a horizontal sectional view on the line L1 4 in Figure 1.

Figure 5 is a View of an outer top Wall block.

Figure 6 is a top plan view of an outer Wall block.

Figure 7 wall block.

Figure 8 is a top plan view of an inner wall block.

Figure 9 a sectional view of a corner ofthe Wall construction.

Lil-e nrnnerals of reference indicate corresponding parts in the various figures.

`Referring to the drav-rings, the construction of the wall is begun by placing the starting course, formed by the blocks 10 and 11 onV to the prepared foundation These blocks are permanently secured 'to each other-at 13 and form a rigid base, and have the tongue 1-(1 adapted to be inseried into the groove of another block laid thereon.

.is an enlarged detail of an inner The main front blocks 15 are formed with the tongue grooves 16 and are backed on the used surfaces with asphalt 17 and tar paper 18, the latter overlapping at one end to cover the joint with the next block.

The intermediate blocks 19 are similarly.

formed to the main blocks 15 having the tar paper and asphalt but in place of the grooves 1G they have the tongues 2O fitting into said grooves 1G, each of the blocks 19 overlapping tvvo blocks 16 or in other Words crossing the joint.

The inner blocks 21 are formed with the grooves 22 and the central hollow abutnients 23 and end abutments 24 faced with the building cotton 25 secured by asphalt or other adhesive. These abutments engage the front Wall blocks 15 on the tar paper side and the cotton faced central abutments 23 eover the joints of the front blocks.

The locking kblocks 26 and 2are introduced at the front and the rear respectively and are formed of face portions 28 and 29 having the tongues 30 and 31 and 32 and 33 and the interlocking inner portions 34 and 35, which tit into one another and are lined with building cotton 3G and 37 at the meeting faces and` also at 38 and 39 to meet the cotton covered backs l0 and 41 of the face portions 28 and 29. The interlocking inner portions of the looking blocks 26 and 27 are longer than the face portions 28 and 29 thereby engaging the backs of the contiguous blocks.

The locking blocks are introduted at intervals preferably in the centres of the main blocks and in the saine courses as the intermediate blocks and eflectually hold the inner Wall blocks to the outer Wall blocks.

The construction of a corner is shown at 12 in Figure 9, but it is obvious'that various turns and' different angles and features of the building may be accon'imodated and still contain the invention, which is the peculiar form of the blocks and the provision for tight joints, as Well as the security afforded by the locking means.

The advantages of this Wall are manifest to the practical man for the many troubles incident to wall constructions are taken care of and a close Wall provided for all climatic conditions as it Will insure Warmth in cold Weather and be cool in ivarm Weather 1 and at the saine time be steadfast in its position and impervious to the elements.

What I claim is l. In wall construction, a plurality ot main blocks in courses, a plurality of intermediate blocks in courses, between said main blocks and 'forming therewith a front to the wall, a plu ality ot main rear blocks having abutments meeting the joints ot the front blocks, a plurality ot intermediate rear blocks and locking blocks front and rear having .interlockingl inner portions and introduced in said intermediate cours-es.

2. In wall constructions, a plurality il main blocks with asphalt and tar paper hacks forming an end overlap, a plurality ot intermediate blocks in courses, between said`inain blocks and torining therewith a iront to the wall, a plurality of main rear oloclis having ahutments meeting' the joints of the front hloclis, a plurality of intermediate rear blocks and locking blocks front and rear having interlocking' inner portions and introduced in said intermediate courses.

il. ln a wall constructionr` a plurality of main blocks in courses a plurality of intermediate blocks in courses between said main blocks and forming' therewith a front to the Iwall,` a plurality ot main rear blocks having a fabric hacking' and aloutments meeting the joints oi' the trOntblOCkS, a. plurality oi intermediate rear hloclrs and locking blocks t'ront and rear having inter locking inner portions and introduced in said intermediate courses.

In wall construction7 a plurality of main blocks in cours-es, a plurality ot' inter- 4and rear blocks and containing interlocking inner portions and introduced in said intermediate courses.

5. In a wall construction, a plurality ot' main blocks in courses a plurality oi intermediate blocks in courses between said main blocks and forming there `-ith al tro-nt to the wall, a plurality ot main rear blocks having central hollow ahutments and end abutments meeting joints ofv the front Wblocks, a plurali-ty ot' intermediate rear blocks and locking blocks front and rear having interlocking inner portions and introduced in said intermediate courses.

In a wall construction, a plurality ot' main bloc is in courses, a plurality ot intermediate hloclts in courses, between said main blocks and toi-ming therewith a iront to the wall, a plurality of main rear blocks having central hollow ahutnients with fahr'ic meeting surfaces, a plurality ot' intermediate rear blocks and locking blocks front and rear having interlocking inner portions and introduced in said intermediate courses. j
